Abstract: The storage and retrieval of medical information is provided by use of a database that facilitates accurate clinical audit, research and/or presentation activities. Comprehensive patient information may be retrieved based on patient descriptive categories including the anatomy, pathology or clinical presentation, treatment and outcome factors of each case. The categories include data options that may be organized in the form of a hierarchical tree that has branching levels of data options with decreasing specificity. Data from the various levels may be compared, as well as data between individual categories. In some embodiments, selected multimedia data may be accessed based on criteria from data options of the patient descriptive categories.
